Tourists are looking for information about a place in which they have not been before, which worsen the selection of places that fit better with user’s preferences. Recommendation systems have been fundamentally applicable in tourism, suggest suitable places, and effectively prune large information from different locations, so tourists are directed toward those places where are matched with their needs and preferences. Several techniques have been studied for point-of-interest (POI) recommendation, including content-based which builds based on user preferences, collaborative filtering which exploits the behavior of other users, and different places, knowledge-based method, and several other techniques. These methods are vulnerable to some limitations and shortcomings related to recommendation environment such as scalability, sparsity, first-rater or gray sheep problems. This paper tries to identify the drawbacks that prevent wide spread use of these methodologies in recommendation. To improve performance of recommendation systems, these methods are combined to form hybrid recommenders. This paper proposes a novel hybrid recommender system which suggests tourism destinations to a user with minimal user interaction. Furthermore, we use sentiment analysis of user’s comments to enhance the efficiency of the proposed system.</p>2018-03-30T12:52:41-05:00##submission.copyrightStatement##http://www.researchplusjournals.com/index.php/IJSMS/article/view/396Algebraic Verification Algorithm2018-05-24T12:34:42-05:00Areej M Abduldaimareejmussab@gmail.com<p>Authentication over insecure public networks or with untrusted servers raises more concerns in privacy and security.Modern algebra is one of the significantfields of mathematics. It is a combination of techniques used for a variety of applications including the process of the manipulation of the mathematical categories. In addition,modern algebra deals in depth with the study of abstractions such as groups, rings and fields,the main objective of this article is to provide a novel algebraic verification protocol using ring theory. The protocol is blind, meaning that it detects only the identity, and no additional information will be known anything about the prover (the biometric) to the authenticating server or vice-versa. More officially a blind authentication scheme is a cryptographic protocol that comprises of two parties, a user (the prover) that wants to achieve having signs on her messages, and a signer (the verifier) that is in ownership of his secret signing key. In this paper, we employ the algebraic structure called central Armendariz rings to design a neoteric algorithm for zero knowledge proof. The proposed protocol is established and illustrated through numerical example, and its soundness and completeness are proved.This method gave two important properties for the central Armendariz zero knowledge protocol compared with other known protocols.</p>2018-03-30T13:06:32-05:00##submission.copyrightStatement##http://www.researchplusjournals.com/index.php/IJSMS/article/view/397Using mobile device in-store: which implications for retailers?2018-05-24T12:34:41-05:00Prof.ssa Silvia Bellinisilvia.bellini@unipr.itProf.ssa Maria Grazia Cardinalimariagrazia.cardinali@unipr.itDott. Simone Aiolfisimone.aiolfi@unipr.it<p>The widespread mobile connectivity has not only changed the way we interact and communicate, but has significantly impacted on consumer decision-making process. Consumers in a retail setting use mobile devices with different purposes: finding information on the web, comparing pricing and purchasing goods and services. Therefore, it becomes crucial to understand how the mobile influences the decision-making process as well as the purchasing decisions in-store. This topic is of great importance in grocery sector since retailers and manufacturers devote many investments in instore marketing activities with the aim to influence consumers’ decisions and stimulate impulse purchases. The rise of the mobile channel has produced disruptive changes in shopping habits designed to gradually reduce the effectiveness of in-store marketing levers in influencing shopping behavior. Manufacturers and retailers are worried that the mobile could potentially distract the customer from the products and services offered within the store. Our research intends to explore the impact of in-store mobile technology use on shopper behavior instore in order to understand its effects on planned versus unplanned purchases. According to our preliminary results, consumers using mobile technology instore make less unplanned items and fail to purchase more planned items. Moreover, the use of mobile technology negatively affects shoppers’ ability to recall in-store stimuli. Our findings are interesting for both retailers and manufacturers who are looking for new ways to better address their marketing efforts and increase consumers’ engagement instore.</p>2018-03-30T13:28:22-05:00##submission.copyrightStatement##
